Well although I'm not a lady I know my mistress loves her pink magic wand. I have yet to see it fail to give her a very hard orgasm. Actually I get a little jealous of it sometimes... https://www.healthyandactive.com/trinity-7-speed-wand-massager/ It's like this one but they have several models on eBay for $15 to $20. You can buy several attachments also.
Likewise, not a lady, but my Wife has said she doesn't need to look for a new vibrator now we have the Lovehoney wand massager. She doesn't like and has never got off with penetrative vibrators that mimic a penis but with this she has very nice orgasms.
